QUESBA IS A SCAM FOR TUTORS
1) When on has an issue as a tutor and try to contact them they never reply even if you send dozens of emails, no response.
2) Tutor who doesn't have PAN NUMBER may be because are not citizens of the that country where this no is used, are not paid their hand earned money by answering questions, even if your ratings are 99%.
When you try to follow with them your Emails gets ignored. Why not just reply and say it’s not possible for you to be paid or limit the tutor applications to those countries that use PAN NUMBERS. PATHETIC.
